Yes, your C++ implementation should be written in such a way that the
interface methods of the UNO API it implements can be called by
arbitrary threads, in arbitrary patterns.
Using the ":affine" suffix in component_getImplementationEnvironment
(see
http://hg.services.openoffice.org/DEV300/file/f387649cb501/connectivity/source/drivers/ado/Aservices.cxx#l121
for an example) should ensure that the UNO runtime takes care of this,
right?
That would be the ":unsafe" thing (which is weaker than ":affine," if I
understand correctly), right? Kai Ramme should know...
